IoP Collaboration graph with R igraph

My boss asked me to make a nice slide for a presentation showing the collaborations between researchers at our institute. I have a mountain of other work to do, so in the name of procrastination I spent the afternoon playing with the igraph R library:

If you have ruby, rubygems, rake and the Perl module Spreadsheet::ParseExcel installed you can just grab the Rakefile from https://github.com/cassj/my_bioinfo_scripts/blob/master/Rakefile.iop_connections and run ‘rake’. It’ll download all necessary scripts and datafiles, convert xls to csv and run the script to generate the plot for you. I just tried it on RHEL6 and it works for me. I had to make a quick change to the code to get it working with a recent version of igraph but I’ve pushed the change to github.
